Cologne

The first urban settlement on the grounds of modern-day Cologne was Oppidum Ubiorum, founded in 38 BC by the Ubii.

Cologne is considered the most flood-prone European city.

Cologne is home to 90,000 people of Turkish origin, making it the second largest German city with a Turkish population after Berlin.

Cologne's city centre today is characterized by modern architecture, with a few interspersed pre-war buildings reconstructed due to their historical importance.

The sheltered climate in southeast North Rhine-Westphalia allows feral parrots, such as the rose-ringed parakeet, to survive through the winter in Cologne.
